Specification forming part df Letters Patent No. 36,268, dated August', '26, 1862.

had'to the accompanying drawing, and to the letters Iof reference marked thereon, makinga part of this specification. The nature of my inventiou'consi'stsin the arrangement and combination. of two curved. sides projecting back of the carriage axle, each having a curved slot or-opening, in which the ends of a vibrating cross-bar operate up and down, the erossbar being attached to afroller on the platform ofthe machine by connectingrods, and the roller is'operated half round by moving an upright lever orward'orbackward, which operates the cross-bar to raise and lower the teeth or rake. f

To enable others skilled in the art to make and use my invention, l will proceed to describeits construction 'and operation.

A re} )resents the'carriage wheels and axle, B the platform, and C the drivers seat, D the shafts. v ExE represent the ordinary curved steel teeth, which areattached tothe Iear side of platform B by a common hook and eye, G.

' H H are the projecting sides, attached to the sides of platform B immediately above the carriage-axle, extending back andcurving up- \va rd,- and wider at;4 their outer ends.. They are intended to bel made of wood or iron, about four feet in length and: about three.4 feet in width at their. outer ends. .At the outer end oi' each is a curved opening or slot, J, in which the 'ends oi a horizontal cross-bar, K,operate np and down in a curve. Underneath this cross-bar K is a long dat steel spring, L, fastened to each end of bar'K to add elasticity to the pressure of the teeth. There are also long eyes M, ot streng wire, fastened to the ylower side of barK, extending downward about six inches; in. which the teeth work up and down,

and are raised and supported lin their`pr'oper positions. Connecting-rods N, of `strong wire or rod-iron,hooked'together in a joint, P, in

vthe'ce'nter,` are fastened rmly, one end to the end of cross-bar K and the other end 't'oj the top side of roller Q. There are'two of these jointed connecting-rods, one on each side of the machine, so as to raise and lower the crossbarK and teethl more 'regularlyv and easily than by the usual devices of raising and low ering the teeth by a center draft.

R represents an upright lever, (which is op eratedby the right hand of the driver,) which is fastened permanently to the'center of 'roller' Q. y The 'roller rests upon the platform B,' across the machine parallel with tl1e carriage.- la xle,'and is held to the platform by two round clips, S, in which the roller revolves. ,Ast-he" driver presses the lever -R forward the roller. revolves forward about oiielh'alfround, drawl ing forward the connecting-rods N, thus raising the bar K. and the't'eeth, which drop the hay or grain. When thedriverlets go the lever R the cross-bar. K falls in itsslot J and drops the teeth by their own weight to theground,

the teeth again commence rakingnp the grain center,'by which the' teeth are 'raised above and near to the carriage-axle, this invention vraises the teeth half the length of the teeth farther back from the axle,'and thus works easier andbetter'. t l

What I claim as n'iy invention, and desire to secure by Letters Patent, is i The construction and arrangement of the 'slotted sides H H, in combination with the vibratingcross-bar K and connectngfrods N, 'as arranged with the roller Q, for the purpose of raising the teeth with greater regularity and facility. as herein described.
